Какой калибр лучше 5.45х39 или 7.62х39 от Сутаева

Which caliber is better: 5.45x39 or 7.62x39, according to Sutaev Eduard Cherchesov "In the 1980s, due to renewed doubts, intensified trials were organized. During these trials, firing was conducted at specially mounted fascines set at a distance of 100 meters. Grass, reeds, or bush branches with a diameter of 2-4 mm or 8-12 mm were fixed to them, arranged in four rows in a checkerboard pattern. During firing, bullets passed through a cardboard screen, a fascine, a sheet of plywood, and a shield made of 25 mm boards. The tests involved 5.45 mm, 5.56 mm M193, and 7.62 mm model 1943 cartridges. Grass and reeds, as before, did not affect the dispersion characteristics or stability of the bullets. When firing through small bushes, the number of oval holes in The 5.45mm and 7.62mm bullets had the same penetration rate – 30% each, while the M193 cartridge had 50%. In large brush, the number of ovals increased to 85, 45, and 80%, respectively. Moreover, the 5.45mm bullets had the smallest penetration behind obstacles, while the M193 bullets had the largest. All bullets maintained their lethality, penetrating 25mm boards at distances of 3 and 15 meters behind fascines. This once again confirmed the virtually equal resistance of small-caliber (5.45mm and 5.56mm) and normal-caliber (7.62mm) bullets when penetrating light obstacles. (c) Debunking Myths About the 5.45x39 Caliber by Sutaev Hi everyone, sorry, I filmed the video after training. I train a lot, I don't sleep much, so I was a bit confused, but I'm working on it. I'm tired of hearing tales about the 5.45 with its offset center of gravity, how it hits the leg and completely blows my mind. It feels like 90% of the Army's bread-cutters were. There are so many myths, so many misconceptions. I'm tired of actually debunking these myths, but the point is, it needs to be done; these myths are the cause of all the problems! If you like this topic, be sure to share my videos and let me know what else needs to be filmed. 1. The severity of soft tissue injuries can be higher than with the 7.62. 2. Low recoil impulse and high flatness. 3. Light cartridge weight (10.2 grams versus 12.1 for the 5.56 and 16.2 for the 7.62). 4. High bullet velocity. 5. Penetration at short and medium ranges is higher than with the 7.62×39, but this applies exclusively to the first versions of the cartridge with the PS bullet. (7N6/7N6M). With the PP (7N10) and BP (7N22) bullets, armor penetration is comparable to that of the 7.62mm cartridge (7.62×39) model 1943, while with the BS (7N24) bullet, armor penetration is higher than that of both the 7.62mm cartridge (7.62×39) model 1943 and the 7.62mm rifle cartridge (7.62×54) model 1908. 6. Better flatness than that of the 7.62x39 Disadvantages Low penetration of simple cartridges at long ranges, BUT lower armor penetration at longer ranges. This applies exclusively to the first versions of the cartridge with the PS (7N6/7N6M) bullet. In the variant with The armor penetration of PP (7N10) and BP (7N22) bullets is comparable to that of the 7.62mm cartridge (7.62×39) model 1943, while the BS (7N24) bullet version has higher armor penetration than both the 7.62mm cartridge (7.62×39) model 1943 and the 7.62mm rifle cartridge (7.62×54) model 1908. The tendency to ricochet and low bullet stability are a slight misconception; all bullets are prone to ricochet. I also want to clarify for everyone: many people say they fired from an AK-74 with a PBS suppressor with rubber stoppers. This is a fake. Yes, there was such a cartridge, but it doesn't work with stoppers; it was only intended for the PMS, and This cartridge has been discontinued since 1980, as it was ineffective and had numerous problems with jamming in the barrel. Good and accurate comments!!! Student To penetrate something, you have to hit something. In Soviet times, comparative firing tests of the 5.45 and 7.62 calibers were conducted. As a result, hitting individual and group targets in bursts required half as many 5.45 rounds as 7.62 rounds. Felix Dzerzhinsky The energy of the 5.45 and 7.62 at 300 meters is 612 J and 842 J, respectively. However, the 5.45's high velocity makes aimed fire easier, especially at moving targets, as its velocity at this range is 597 m/s and its flight time is 0.41 s, compared to 453 m/s with a flight time of 0.53 s for the 5.45. The NATO 5.56 will certainly be more versatile (741 J, 607 m/s, 0.41 s). Mayrbek-Abdulbekovich Baibatyrov In 1992, we tested a military armored carbine. It penetrated an SVD, an AKS, and a 5.45, but not an AKM. Also, if you need a good tuning for your weapon, contact my store https://www.shooter-man.ru/.
